I posted this previously and got zero response and the post is now archived. Hoping for better luck this time.

We have rolled Firefox ESR to all of our computers. On some of them the Maintenance Service is working correctly and installing updates with no user interaction. On other computers, users are getting a UAC prompt to enter admin credentials to install updates. I have tried various changes that I have found across the web from Deleting the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MozillaMaintenance\Security to uninstalling and re-installing the Maintenance Service. All of the users/computers have the same policies applied via Group Policy (Application Autoupdate: Enabled and Disable Update: Disabled) and are not local admins.

What's the question?

How to get Firefox to install the updates in the background, like it is supposed to, without giving end users the UAC prompt.

I may have found a workaround. In testing on 2 machines, if I create a scheduled task that runs the following command "firefox.exe --backgroundtask backgroundupdate" it seems to update successfully. I am getting ready to role this out to a small subset of users to see if it works in production.

The recommendation from the team is that you open up a bug in Bugzilla. We can do some logging and figure out what's going on.
